You know, I'm not 100% sure if this ever worked. If they manually type your name with an @ in front, it will implicitly work - but I don't recall we've ever had this feature to convert someone pinging the webhook into a useful ping on the other side. I don't even see a way to do that within Discord's UI. You can manually <@######> ping it, but there's no normal mention button. Replies seem to work correctly, but we're not really doing the normal mention logic there.

Since the webhook is really just changing it's name and icon for each message, I suppose if we wanted to start doing this it'd have to keep track of the last person who sent a message with it. The obvious issue there is if someone else speaks between, it might tag the wrong person.
